Introduction

The examination of organisms on earth privides insight into evolutionary and selective breeding processes.

The well-known and widely used iris data set (Fisher’s or Anderson’s) gives the measurements in centimeters of the variables sepal length, sepal width, petal length, and petal width. The data comprise measurements from 50 flowers from each of 3 species of iris. The species are Iris setosa, versicolor, and virginica.

App Location

The app can be accessed here: https://peernisse.shinyapps.io/plotExplorer/

Presentation Source Code

Iris Species

Below are images of each ofthe three iris species for a little bit of reference while using the app. Each species has different lengths and widths of sepals and petals. The ratio of sepal and petal length is somewhat unique to each species.

Iris setosa

Sp. Setosa

Iris versicolor

Sp. Versicolor

Iris virginica

Sp. Virginica

Iris Anatomy

The image below points out the primary structures of an iris flower, including the petal and sepal, which are the main parameters included in the Iris dataset.

Examples

Below are examples of the scatter plot and boxplot you can interact with within the app. Within the app, you can select species, select x and y variables for a scatterplot, and select the faceting variable used in the boxplots.

NOTE: While plotly ineraction exists in this presentation, it is not included in the app. The interactivity in the app is contained in the R Shiny code only.
